I have read so much confusing info here and tried pouring over the TOS for both services, but what's the final word. Can you run Adsense and Chitika on the same page or not?
No, Adsense doesnt allow this...I'm not sure about Chitika, but this is straight from the Adsense policy
How would that classify Chitika as noncompeting? The way I see it, Chitika is a direct competitor of Adsense, regardless of how the ads are being displayed.
When it comes to the TOS, it is always best to ask Google yourself and get a definitive answer directly from them. However I might also suggest you search Google for "adsense chitika same page" and read through the results there.
